M.2 drive backplanes
Use the section to understand the cable routing for the M.2 drive backplanes.
The server supports one of the following M.2 drive backplanes:
 | |
1 | M.2 x4 non-RAID SATA/NVMe 2-bay backplane |
2 | M.2 x1 RAID NVMe 2-bay backplane |
3 | M.2 RAID SATA/NVME 2-bay backplane |
M.2 x4 non-RAID SATA/NVMe 2-bay backplane
Power cable routing

| From | To |
|---|---|
| 1 Power connector on the M.2 drive backplane | 1 M.2 power connector on the system board assembly |
Signal cable routing
The M.2 drive backplane supports SATA, NVMe, or RAID cable connection.

Note
The following illustration shows four NVMe cable connection options, but the four options are mutually exclusive. Select one of them based on your scenario.
| From | To |
|---|---|
| Signal connector on the M.2 drive backplane | 1 PCIe 1 |
| 2 PCIe 3 (one processor installed) | |
| 3 PCIe 8 | |
| 4 PCIe 10 |
